HORSE SHOE -MACHINE Specification of Letters Patent.

Patented Dec. 17, 1907.

Application filed December 3. 1904. gerial No. 235337.

To all whom it may concern:

Be it known that I, ARTHUR SMITH, a citizen of the United States,residing at Easton, in the county of Northampton, State of Pennsylvania,have invented certain new and useful Improvements in Horseshoe-Machines,of which the following is a specification.

The object I have in view is to construct a machine for squeezing theends of billets, and

bending and forming them, in the manufacture of horseshoes, whichmachine will be composed of few moving parts, will be expeditious inoperation, not liable to get out of order and can be operated at aminimum of.

expense, and can be readily adjusted to accommod ate different sizes andstyles of shoes. I attain these objects by means of the mechanismillustrated in the accompanying drawings, in which,

Figure 1 is a plan view of a machine embodying my invention. Fig. 2 is asection taken on the lines 2,-2, of Fig. 1. Fig. 3 is a section taken onthe lines 33 of Fig. 1. Fig. 3 is a detail view of the adjustable cam.Fig. 4 is a section taken on the lines 44 of Fig. 1. Fig. 5 is a sectiontaken on the lines 55 of Fig. 1. views of parts of the mechanism showingthe operation of upsetting the ends of the billet and bending it toshape. Y

In all of the several views like parts are designated by the samereference characters.

The machine comprises 1, means for squeezing the ends of the billet toprovide for the desirable extra thickness of the heels; 2, means forbending the billet to a U-shape, and 3, means for forming the billet tothe finished shoe. I/Vith, these principal portions the machine alsocomprises other desirable features, such as means for alining the billetwhen itis presented for action to the squeezing and bending mechanism,and means for adjusting the various mechanism for wear and toaccommodate different sizes and styles of shoes. l/Vhen the occasiondemands the squeezing means may be disconnected, or omitted altogether,or the bending and forming mechanism, one or both, may be omitted ordisconnected.

In carrying out my invention I provide a support 1, which comprises sidemembers 2, 2, cross members 3, 3, and a horizontal member or table4.These members may be formed of a single casting. The support 1 is Figs.6 and 7 are enlarged I mounted upon standards or legs 5, so that it maybe raised to an elevation which will be convenient. A main shaft 6 iscarried in bearings 7 in the side members 2, and is provided at one endwith a gear wheel 8. This gear wheel is rotated by suitable mechanism,that shown consisting of an intermeshing pinion 9 carried by a shaft 10and provided with fast and loose pulleys 11. These pulleys connect witha. belt and countershaft and a suitable belt shifter (not shown). Bythis means the shaft 6 may be rotated at will.

The bending die 12, shown in broken lines in Fig. 1, is carried upon aslide 13, mounted in ways 14, on a plate 15 (see Fig. 4). The die is ofthe configuration of the finished shoe, and has a flange 12 around theupper edge to prevent the shoe from rising during the bending andforming operations. The plate 15 is secured by bolts 16 to the sidemembers 2 and rests upon the table 4. The opposite end of the slide 13from the die is bifurcated, as shown, for the admission of a pitman 17connected thereto by a pin 18. This pitman 17 is secured to a crank 19on the shaft 6 so that the slide 13 and die 12 may be reciprocated bythe rotation of the shaft 6.

On each side of the slide 13 is a slide 20, mounted in ways 21, formedin the table 4. These slides 20 are retained in place by the plate 15,and are provided with bifurcated ends 22 within each of which isarranged a pitman 23 secured by a pin 24 and provided with an eccentricstrap 25. Each of these straps surrounds an eccentric 26 carried by theshaft 6. The two eccentrics are of the same throw and secured to theshaft 6 at the same angle so that the slides 20 may be simultaneouslymoved an equal distance. The slides 20 are arranged however, so as to bemoved at a different period of time from the slide 13. Each of theslides 20 carries a die 27, provided with a projecting portion 28 forsqueezing the extremities of the billet 29. The dies 27 are secured tothe slides 20 by means of bolts and nuts 30, and adjustment is provided'by means of a slot 31 to ac commodate different lengths of billets.

A cross member 32 having a flat upper surface 33 connects the sides 2,2, of the sup port 1 and serves as a table for supporting the billet.Alining rods 34 serve as a means to retain the billet while it is beingsqueezed and bent with its center coincident with the center of themachine. These rods are carportions 37 of the side members 2.

ried by brackets 35 having securing screws 36 so that the rods may beadjusted to accommodate different lengths of billets.

A means for forming the billets to shape is provided. This means is asfollows: Slides 38 are mounted in ways, out in projecting That portionof each projecting portion 37 toward the dies, is inclined, forming abending surface or cam 36, and constituting a fixed abutment. Above eachslide is provided an extension 39, (see Fig. 5), for holding down theslide while the horseshoe is being bent. At one corner of each of theslides 38 is ar ranged a roller 40 which is caused to engage with thebillet, and in conjunction with the die 12 and cam 36, bend the billetto the desired shape.

The slides 38 are arranged to be simultaneously brought together, fromthe position shown in Fig. 6 to that shown in Fig. 7 to bend the shoearound the die by means of the following mechanism: Each slide 38 isprovided with a roller 41.. gaged by a cam 42 mounted upon a slide 43.The other extremity of the slide 43 is bifurcated and provided with aroller 44. The roller 44 is engaged by an adjustable cam 45 carried uponthe shaft 6. The slide 43 is mounted in ways 46 and 47 and is engagedwith the cam 45 by means of a spring 48.

As a further support for the back of the cam 42 a roller 49 carried by ablock 50 is provided. This block is supported upon a bracket 51 boltedupon the support 1, and is secured in place by means of a bolt 52passing through a slot 53. Accurate adjustment is secured by means of abolt 54 provided with a lock nut 55. In order to accommodate shoes ofdifferent sizes, the securing bolt for the cam 42 passes through a slot56. Set screws 57 passing through ears 58 limit the outer movement ofthe slides 38.

The cams 45 are made adjustable so as to accommodate different sizes andshapes of shoes. The construction of the cam is shown at Fig. 3?. and isprovided with fingers 45 which grasp the shaft 6, and a bolt 45 whichconnects it to the gear 8, or a disk 45". A bolt 45 permits accurateadjustment.

The slides 38 are covered by a plate 59, secured in place by bolts 60and supporting the extensions 39. The bolts 60 pass through slots 61 inthe slides 38 so as to permit the latter to move. Springs 62 serve toretract the slides 38 and keep them in constant engagement with the cams42. Each of the springs is connected to a standard 63 and 64 carried bythe slide and main frame respectively.

The earns 45, 45 are each alike as to configuration and angle of throw.They are so This roller is enshaped (see Fig. 3) as to give a quickforward impulse, and in conjunction with the retracting springs, a quickreturn.

In operation, the shaft 6 being constantlyrotated, the billets 29 aresuccessively placed upon the table 33 and accurately alined by means ofthe rods 64. The. eccentrics, cranks and cams are so arranged that theslides 20 will first move, engaging the dies 28 with the ends of thebillet and thereby squeezing them as shown in Fig. 6. This will form thedesirable thickness at the ends of the billet to make the heel portions.The slides 20 will then be immediately withdrawn and the slide 13advanced engaging the die 12 with the center of the billet, moving itinto contact with the cams 36, 36 and will bend it. Further movement ofthe die 12 will continue to bend the billet and engage it with therollers 49. At this time the earns 45 will have engaged with the rollers44 and moved the slides 43 to engage the cams 42 between the rollers 41and 49, which will move the two slides 38 toward. each other and forcethe heels of the shoe between the rollers 40 as shown in Fig. 7, the die12 being at the same time advancing. The forming operation willtherefore be compounded of the movements of the slides 38 and die 12.The shoe will be prevented from being forced upward owing to the actionof the die and slides on the beveled billet by means of the flange 12,and similarly the slides 38 willbe held down by means of the extension39. The slides 38 will be next withdrawn by means of the springs 48 and62, and allowing the completed shoe to be removed. The die .12, andsqueezing dies will be withdrawn,

and the machine will be ready for squeezing and bending another billet.

Different sizes and shapes of shoes may be operated upon by substitutingsuitable bending dies and adjusting the position of the squeezing dies,alining rods and other portions of the machine to correspond.

Having now described my invention what I claim as new and desire tosecure by Letters Patent, is

A machine for bending and formin billets into horse-shoes, which has theben ing die moved by a crank, whereby a continuous movement will besecured, and a forming die moved by a cam whereby an irregular movementwill be secured, there being means for adjusting the position of the camin relation to the crank, so that the time of forming in relation to thetime of bending can be varied.

This specification signed and witnessed this seventh day of November,1904.
